• src/tools.ts:249-268 (handler)

  The handler for the 'bimi_vmc' tool, which performs an API call to /v1/vmc/check to retrieve BIMI/VMC information for a domain.

  async ({ domain }) => {
    try {
      const result = await apiPost(
        "/v1/vmc/check",
        { domain },
        { prefix: "/portal-api", timeout: 15000 }
      );
      return { content: [{ type: "text", text: formatJson(result) }] };
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: `Error: ${error instanceof Error ? error.message : String(error)}`,
          },
        ],
        isError: true,
      };
    }
  }

    },
    async ({ domain }) => {
      try {
        const result = await apiPost(
          "/v1/vmc/check",
          { domain },
          { prefix: "/portal-api", timeout: 15000 }
